Lyme disease is caused by the bacterium Borrelia burgdorferi and is usually transmitted to humans through the bite of an infected blacklegged tick, also known as the deer tick. These ticks are most commonly found in wooded and grassy areas, particularly in the Northeastern and upper Midwestern United States, but can also be found in other parts of the world.
Ticks become infected with the bacteria when they feed on small mammals such as mice and squirrels that are carrying the bacteria. If an infected tick then bites a human and feeds on their blood, it can transmit the bacteria into the person’s bloodstream, leading to Lyme disease.
It’s important to note that not all ticks carry the bacteria that cause Lyme disease, and not all tick bites lead to infection. If you’ve been bitten by a tick, it’s a good idea to monitor the area for any signs of infection or illness and to seek medical attention if you develop symptoms such as a rash or fever. It’s also important to take steps to prevent tick bites, such as wearing protective clothing and using insect repellent.
